CD146/MCAM Protein, Human (HEK293, His)

The CD146/MCAM protein is critical for maintaining endothelial monolayer integrity and cell adhesion in vascular tissue. Its expression promotes the interaction of melanoma cells with the vasculature and may contribute to tumor spread through the bloodstream. CD146/MCAM Protein, Human (HEK293, His) is the recombinant human-derived CD146/MCAM protein, expressed by HEK293 , with C-His labeled tag.

The CD146/MCAM protein plays a crucial role in cell adhesion and maintaining the integrity of the endothelial monolayer at intercellular junctions in vascular tissue. Its expression enables melanoma cells to interact with the cellular components of the vascular system, potentially promoting the spread of tumors through the bloodstream. During embryonic development, CD146/MCAM may function as an adhesion molecule in neural crest cells. It acts as a surface receptor, initiating the tyrosine phosphorylation of FYN and PTK2/FAK1, and leading to a transient rise in intracellular calcium levels.

80-110 kDa (glycosylation)

Greater than 95% as determined by Tris-Bis PAGE.

Lyophilized powder.

Lyophilized from 0.22μm filtered solution in PBS, pH 7.4. Normally 5 %-8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
